GnAIn SHOCKER.

Application filed December as, 1922'. Serial 1%. 609,421.

My invention relates to certain improvements in a machine for shocking graimsuch as illustrated in my prior United States Letters Patent No. 1,512,769, dated ()ctober 21, 192 1.

Bundles of grain, as they are delivered from the binder deck of a harvester binder, do not, as is generally supposed. assume a truly circular form in cross section; but instead. assume an elliptical form and are delivered along and from the binder deck with the longitudinal dimidiate plane or" the major .axis thereof, parallel to t-heplane of the binder deck.

In order to form a shock which will reasonably withstand the force of the'elements, it is essential that the individual bundles composing the shock be set at an acute angle to the vertical centre of the shock with the aforesaid major axes of the elliptically formed bundles lying in a line parallel to the longitudinal centre line of the base of the shock. To accomplish this result, the said major axis of each bundle must be main tained in a certain definite position from the time the bundle leaves the deck of the binder until it is placed in its correct position in the shock forming basket.

One object of my invention is to provide mechanism whereby bundles of grain may be received successively tromthe binder deck, the aforesaid major axis of each elliptical bundle being definitely maintained while the bundle is being positioned on the table of the shocker and while a second bundle is likewise positioned on the tablein proper angularly opposed relationship to the first bundle, and the two so positioned bundles gripped and maintaincd in their proper re lation one with the other, by a grapple, which positively places the aforesaid pair of bundles in the basket of the shocker in the correct relationship for forming a shock of the character described above.

Referring to Figs. 1 2 and 3. 1 isthe main frame of the machine A for shocking grain, which is attachedto the binder B. as illustrated in the application h'ereinhefore referred to. 2 is the'main shaftof the shocker having a traction wheel 3 at ezicherid. as shown in Fig. 1. v i

4 designates the guide bars over which the bundles of grain are carried, forming a slatted table 5, as clearly shown in Fig. .3. The barsare secured rigidly to the main frame 1. Secured to the table 5 are three fixed fingers 6 against which the first bundles rest.

7 designates the receiving tongs. There are two pairs ottongs in the present in stance. The tongs positively grip the bandle of grain and transfer it in position to be located properly. As the tongs grip the bundle, they tear it away from another bundle beingformed on the table 6, insuring delivery of the bundles from the binder and not depending upon the mechanism of the binder to feed each bundle to the shocking mechanism.

carried into position. forward, it turns the yoke 28 on its pivot,

8 having a curved extension 9 and a short, curved arm 10 pivotedto the long arm at 11. The long arm. of each pair of tongs is pivoted at 12 to a bearing 13 onthe main end, one crank operating one pair of tongs and the other crank operating the other pair of tongs. On the shaft is a spiral gear 22, which meshes with a spiral pinion 23 loosely mounted on the main shaft 2. On the hub of this pinion are clutch teeth 24, which are in'position to be engaged by. the teeth of the clutchslecve 25, which is splined to the shaft 2 so that it can slide on the shaft,- but must turn therewitlrf Back of the sleeve is a'spring 2.6,which rests against a collar 27 secured to the shaft. This spring tends to force the clutch inengagement with The clutch is held out of engagement by a yoke 28, which extends into a groove in the sleeve The yoke is secured to a short shaft 29 and has an arm 3O on which is a sliding block 81 to which is secured a rod 32. The rod extends through a bearing 33 on the yoke. Between the bearing and the block 31 is a coiled spring 34. i The block has a projection 35, which limits its outward movement, Fig. 5;

The'rod has a lateral projection 36, which is engaged by a trigger 37 pivoted at 38 to alever 39, pivoted at 40on the mainframe As shown in Fig. 1 the deck 6 of the binder B is provided with bundle forming and tying mechanism B forming no part of the present invention,

which is operated by a shaft b towwhich. is secured a lever40 connected by a link 40 toone end of a lever, 40 pivoted to the frame 1 of. the shocker A. The opposite end of the lever 40 is connected by a link 4O to an arm 40 secured to the lower end of the pivot shaft 40 of the lever v39, whereby, the lever39 is actuated by the tying inechanismon the binder. A spring 41 tends to hold the trigger in its extended position, but allows thetrigger to turn on its pivot on returning when it passes the'projection on the rod 32.

On the face of the spiralgear 22 is a pin 42, which comes in contact with the block 31, as shown in Fig. 5, after each bundle is As the pin-inoves which withdraws the clutch sleeve 25,.stopping the movement of the shaft 20, the tongs being in position of rest to receive another bundle, as shown in Fig. 1.

VVhenthe block 31 is withdrawn from the path of the pin 42 by the tying mechanism of the binder, the clutch sleeve 25 is moved into engagement with the teeth 24 on the hub of the pinion 23 by the spring 26, and

moved by the spring 26, it will move the latch clear of the path of the pin 44.

As this machine is designed to place two bundles in position to be engaged by the i grapple, and, as the binder delivers one bundle at a time, means must be provided to assemble the bundles side by side. This is accomplished, as follows: a

Pivoted to the main frame, at 46 and at 47, are arms 48 and 49, respectively. These arms are straight and extend above the slat-ted table, when elevated. When turning on their P1170138, they are located below the table and under thetongs.

As the first bundle is raised onto the slatted table by the tongs, the arms 48 and 49 follow upand engage the bundle, moving itout of the tongs, which have opened on their return movement. The arms move the bundle O er the table to its fi al Position against the stationary fingers 6. As the bundle is moved onto the table, it comes in contact with spring-pressed arms 50andf51,

wh ch are pivoted at 52 and 53, respectively,

and extend through slots in the frame formed by plates 54. The 'springs55 are attached to the armsand to pins on the main frame' These spring-pressed arms yieldingly hold the bundle against the arms 48 and 49 and prevent'the bundle moving out of position. y i

The arms 48 and 49 arefcontrolled by cams on a cam shaft 56, journaled in a pair of brackets 57, extending from the main frame of the machine. wheel 58, which meshes with a wheel 59 on the shaft 56. The gears are proportioned twoto one. The arm 48 is aflcenter arm and is located between thehead of the two bundles :rm, Figs. 2. and 3. The arm 48 has a short extension 60 connected by a link 61 to a lever 62 pivoted at 63 to one of the brackets 57. On; the lever is a. roller 64, which rests against the face ofa cam 65,011

,theshaft 56. The cam is so cut as to give the arm- 48 the proper movement" in time with the other mechanism. y 7

The arm 49, which rests against the butt of the first bundle. is controlledby a cam 66 onthe shaft 56 througha lever 67, pivoted at 6.8, and having a roller 69, shown by dotted lines in Fig. 6. Thelever 67 is con- On the shaft 20 is a gear nectedto the arms 49 by a link 70. When the arms '48 and 49 areraised, as in Fig. 2,

they hold the first bundle firmly against thefingers 6.

An arm 71, pivotedto the main frame at 72, moves with the arms 48 and 49 and acts, with the arm 48, as astop and holder for the second bundle,lspacing the butts of the bundles. The arm 71-is connected by a link 73 to a lever 74 pivoted at 68. and having a roller'75, which rests against a cam 7 6 on the shaft 56.

Pivoted to the table 5, at77and at 78, are curved fingers 79 and 80, respectively. These fingers are located below the table, as in Fig. 1, when the bundles are being placed in position. When the second bundle is beinglocated in, position on thetable by the tongs, the fingers 79 and 80 are raised into the position shown in Fig. 2, holding the second bundle against the arms 48 and 71, and allowing the tongs to return to their position of rest, as shown in Fig. 2. The finger v7 9 isconnected to a. lever 81 by a link 82.

On thelever is a roller 83 resting against a cam 84. j

The finger is connected to a lever 85 by a link 86.- On the lever is a roller 87 resting against a cam 88. The several cams on the cam shaft 56 are so timed that each arm will have a movement at the proper time, and, when the arms areall in the raised position, they remain in that position fora given length of time to allow the grapple to engage the bundles and remove them from the table. I

Attached to the binder deck b is a series of slate 99, bent at their outer ends'and at-- tached toa cross bar 100, Fig. 1. The slats and bar form a continuation of the deck 6.

The bar is so located in respect to the tongs that the extensions 9 of the tongs 7'rest on the bar so thata bundle, when released by the binding mechanism, passes directly into the tongs without changing its position.

The tongs positivelyengage'the bundles and move them into the grapple D.

The tongs receive and grasp one bundle while another bundle is held in the binder as it is being tied. The tongs, as they move away from the deck, pull one bundle from the other so that each bundle is a separate unit. This is especially important when tangled grain is handle It will be understood that the bundles, when formed and tied, areoval. The longest axis lies parallel with the surface of the deck, consequently, when the bundle reaches position to be grappled by sides face to face in the shock to make a perfectshock. .By assembling the bundles in th s manner on the table, they w1ll remain in this position while passing through the machine, as both bundles are controlled tively after they leave the table. v

The grapple D, Fig. ,1, has fingers d, cl, which are operated by mechanism timed with the boom 6F, and the meansfor turning the same relative position in which they were held'by the arms.

. When the basket has been loaded with a predetermined number of bundles, it is turned, and its load deposited on the groundto form a shock.

By the above construction, it will be seen that the bundles of. grain are engaged positively by the mechanism as soon as they are released a by the binder and that they are held firmly in their several positions by the mechanism until they are deposited on the groundin the form of a shock.

-In Figs. 7 and 8, a modification is illustrated,-in which a dividing board is substituted for the two arms 49 and 71. 89 designates the dividing board mounted on. a.

stud 90 on the main frame 1 and actuated by a cam 91 through a lever 92 and link93. The arm 48 is actuated by a cam'tifi and link 61 cam shaft 56. I

In Fig. 8, a modification of the means for actuating the clutch sleeve 25* i's'shown.

On the yoke lever 30 is pivoted a dog 31, which in turn carries a pawl 98 pivoted thereto and projecting into the ,pathof movement of a head 94 on arod 95' connected to an arm 96 of a lever 97 pivoted to the frame. The lever 97 is connected to the tying mechanism of the binder. The head 94-of the rod moves past the projecting end [of the pawl, and, on its return movement,

engages said pawl 98 and swings the dog The cams 91 and 65 are on the 31" laterally from under the clutch with-- drawing pin 42*, thereby releasing the yoke 3O and permitting theclutch sleeve 25 to engage the teeth'24 of the pinion 23.

"When the rod 95 is fully retracted, the dog is released and returns into position to be engaged by the pin 42 carried by the gear the tongs, it is stillv in the same position. 22

hen the tongs carry the bundle to a. position on the table, the bundle is arranged on edge, the broad side of each bundle being face to face. This is important, as the bundles must be arranged with their broad bundle assumes an-elliptical form in cross-' and to maintain said bundles with the major axes thereof, in a definite position; I 2.
